Polyatomic ions are ions that consist of two or more atoms that are bonded together and carry an overall charge. These ions typically contain nonmetal elements and are formed when groups of atoms have gained or lost electrons. Most commonly, polyatomic ions include a central nonmetal atom, often bonded to oxygen and/or other nonmetal atoms.
